Lead-Free Manganese Halide Perovskite for Minute-Level Dynamic Time-Gating Anticounterfeiting.

The dynamic time-gating anticounterfeiting based on phosphorescence materials is the current hot topic of research. However, the short change time from nanosecond-level fluorescence false information to μs-level fluorescence correct information makes it easily deciphered just by turning off ultraviolet (UV) light. Herein, we first reported a new type of minute-level dynamic time-gating anticounterfeiting technology based on the ethanol-induced phase transition between the red-emitting CsMnBr crystals and green-emitting CsMnBr crystals.

Effect of histone modifications on fruit ripening.

Histone modifications are canonical epigenetic modifications mediating plant growth and development. Specially, histone modifications play important regulatory roles in plant fruit ripening, directly affecting fruit color changes, soluble sugar accumulation, and fruit softening. In this review, we focus on the effects of histone acetylation and methylation during fruit ripening.

Anti-b diminishes hyperlipidaemia and hepatic steatosis in hamsters and mice by suppressing the mTOR/PPARγ and mTOR/SREBP1 signalling pathways.

Background And Purpose: As a chronic metabolic syndrome, hyperlipidaemia is manifested as aberrantly elevated cholesterol and triglyceride (TG) levels, primarily attributed to disorders in lipid metabolism. Despite the promising outlook for hyperlipidaemia treatment, the need persists for the development of lipid-lowering agents with heightened efficiency and minimal toxicity. This investigation aims to elucidate the lipid-lowering effects and potential pharmacodynamic mechanisms of Anti-b, a novel low MW compound.

Quantitative Measurement of Cooperative Binding in Partially Dissociated Water Dimers at the Hematite "R-Cut" Surface.

Water-solid interfaces pervade the natural environment and modern technology.

The complexity of the partially dissociated structures often makes it difficult to probe them quantitatively.

Polyphenol-Mediated Modulation of Non-Coding RNAs: A New Therapeutic Approach for Hypertension - A Review.

Hypertension (HTN) is a leading risk factor for cardiovascular diseases (CVDs) and a major contributor to global morbidity and mortality. Conventional pharmacological treatments have been effective but are often accompanied by side effects and do not address all pathological aspects of the disease. Recent advances in molecular biology have identified non-coding RNAs (ncRNAs), including microRNAs (miRNAs) and long non-coding RNAs (lncRNAs), as key regulators in the pathogenesis of hypertension.
